Perforce bindings for the LispWorks IDE
control-x p e "P4 Edit"
control-x p S "P4 Submit"
control-x p o "P4 Opened"
control-x p r "P4 Revert"
My purpose in writing this was to give me a simple integration between LispWorks and the Perforce SCM, enough to cut out (say) 90% of the context switches in return for 10% of the programming effort. I might come back and do the rest some time.
